Detail

Hastelloy* C276 (UNS N10276)

Introduction

A-one Alloy  supplies Hastelloy C276 bars from ex-stock. And we keep regular stock for  Hastelloy sheet/plate from EU/US/Japan. We have plenty of Hastelloy C276  ingot in our warehouse which enable us to make fast delivery.

Hastelloy C276 is a  nickel-molybdenum-chromium superalloy with an addition of tungsten designed  to have excellent corrosion resistance in a wide range of severe  environments. The high nickel and molybdenum contents make the nickel steel  alloy especially resistant to pitting and crevice corrosion in reducing  environments while chromium conveys resistance to oxidizing media. The low  carbon content minimizes carbide precipitation during welding to maintain  corrosion resistance in as-welded structures. This nickel alloy is resistant  to the formation of grain boundary precipitates in the weld heat-affected  zone, thus making it suitable for most chemical process application in an as  welded condition.

Although there are several variations  of the Hastelloy nickel alloy, Hastelloy C-276 is by far the most widely  used.

Hastelloy C-276 is widely used in the  most severe environments such as chemical processing, pollution control, pulp  and paper production, industrial and municipal waste treatment, and recovery  of sour natural gas.

Characters

l    Excellent corrosion resistance in reducing environments

l    Exceptional resistance to strong solutions of oxidizing  salts, such as ferric and cupric chlorides

l    High nickel and molybdenum contents providing good  corrosion resistance in reducing environments

l    Low carbon content which minimizes grain-boundary  carbide precipitation during welding to maintain resistance to corrosion in  heat-affected zones of welded joints

l    Resistance to localized corrosion such as pitting and  stress-corrosion cracking

l    One of few materials to withstand the corrosive effects  of wet chlorine gas, hypochlorite and chlorine dioxide

Application

l    Pollution control stack liners, ducts, dampers,  scrubbers, stack-gas reheaters, fans and fan housings

l    Flue gas desulfurization systems

l    Chemical processing components like heat exchangers,  reaction vessels, evaporators, and transfer piping

l    Sour gas wells

l    Pulp and paper production

l    Waste treatment

l    Pharmaceutical and food processing equipment
